'expectedly-consistent' is a compound word formed from 'expectedly' and 'consistent'. 'Expectedly' originates from the Latin word 'expectare', meaning 'to look out for', and 'consistent' comes from the Latin 'consistere', meaning 'to stand firm'.

'Expectedly' and 'consistent' were used separately in English before being combined to form the modern compound adjective 'expectedly-consistent'.

Initially, 'expectedly' and 'consistent' were used independently, but their combination emphasizes a predictable and reliable consistency.
